According to Schneider, Ufert had complained of back pain Monday, eventually leaving City Hall to go home for the day.

“He was having a lot of pain,” Schneider said. “He stayed here for a little while, and finally said he’s got to go home and lay down.”

The pain got more intense as the day went on, Schneider said, so Ufert went to OSF Saint Anthony’s Health Center for tests. Tests showed Ufert had experienced an aneurysm, necessitating the emergency surgery.

Schneider said Ufert was in serious-to-critical condition Tuesday. Ufert was sedated, Schneider said, but not in a coma, as some were speculating. Schneider said city officials were expecting an update on Ufert’s condition later Tuesday.
